Felt like I was steaming through the mainframe knocking those ghosts dead!!  Definitely a cool concept with potential to become even more. 

The controls were a little finnicky here and there, specifically with having to flick the joystick around. Pulling the lever was good though! 

Otherwise, the panic was palpable, and boy did I ever jump out of my seat my first time losing!! Would love to see this fleshed out some day with a story of some kind tied into it. You already had a good start making the little character narrator at the beginning.
